Pass Line vs Don't Pass Bets
What this guide covers
Pass line and don't pass are craps' two foundational, opposing bets, and understanding exactly how they mirror (and don't mirror) each other is essential to reading the table correctly. This guide covers the full mechanical comparison and the practical, social trade-offs of choosing one over the other. For the broader betting picture these two bets anchor, see craps betting guide; for their come-bet equivalents, see come bet vs don't come bet.
How pass line works
Pass line wins on a come-out natural (7 or 11), loses on come-out craps (2, 3, or 12), and then wins if the established point repeats before a 7 appears. It pays even money and carries a 1.41% house edge, making it one of the best-value bets at the table and the default starting point for most new players.
How don't pass works
Don't pass is pass line's structural mirror: it loses on a come-out natural, wins on come-out craps (except the barred number, typically 12, which pushes rather than loses or wins), and then wins during the point phase if a 7 appears before the point repeats. It also pays even money, with a very slightly better house edge of 1.36%.
The one place they don't perfectly mirror: the barred number
If pass line and don't pass were perfect opposites, betting both simultaneously would produce a guaranteed break-even result on every come-out roll. The barred number (12 at most tables) breaks this symmetry deliberately: pass line loses on a come-out 12, but don't pass pushes rather than wins. This single rule is what creates don't pass's slight house-edge advantage — without it, both bets would carry identical edges, and the casino would have no structural way to profit from offering both sides of the same wager.
Side-by-side comparison
| Factor | Pass line | Don't pass |
|---|---|---|
| Wins on come-out | 7 or 11 | 2 or 3 (12 pushes) |
| Loses on come-out | 2, 3, or 12 | 7 or 11 |
| Wins during point phase | Point repeats | 7 appears first |
| Loses during point phase | 7 appears first | Point repeats |
| Payout | 1:1 | 1:1 |
| House edge | 1.41% | 1.36% |
| Can add odds? | Yes | Yes |
Why the house-edge difference is nearly negligible
The 0.05 percentage point gap between these two bets is genuinely tiny — over $1,000 wagered, it amounts to roughly a 50-cent difference in expected value. This isn't a compelling reason on its own to choose don't pass over pass line; it's worth knowing the figure exists, but it shouldn't be the deciding factor for most players.
The social dimension: betting with or against the table
The more meaningful practical difference between these two bets isn't mathematical — it's social. Pass line bettors are betting alongside the shooter and, typically, the majority of the table, sharing in collective excitement when the point repeats. Don't pass bettors are betting against that same outcome, which can feel isolating or even mildly unwelcome at an enthusiastic physical table, even though it's a completely legitimate and mathematically sound way to play.
Why most players choose pass line despite the edge difference
Given the negligible house-edge gap, most players choose pass line specifically for the social experience of betting with the table rather than against it — there's no mathematical error in this preference, since the cost difference is small enough that prioritizing enjoyment over a marginal edge is entirely reasonable. This is one of relatively few spots in casino gambling where the "socially comfortable" choice and the "mathematically optimal" choice are close enough that personal preference can reasonably decide.
When don't pass makes more practical sense
Don't pass can feel like a more natural fit in online RNG play, where there's no physical table atmosphere or shared excitement to consider — the social cost of betting against the table simply doesn't apply in a solitary digital session the way it does live. Some players who exclusively play RNG craps choose don't pass by default for exactly this reason, capturing the marginal edge without any social trade-off.
Odds bets work identically on both sides
Both pass line and don't pass can be backed with an additional odds bet once a point is established, and this odds portion carries zero house edge regardless of which side you're on — meaning the "maximize odds" principle covered in craps strategy guide applies equally whether you're betting with or against the shooter. Don't pass odds pay the inverse ratios of pass line odds (since you're betting on the opposite outcome), but carry the same zero-edge structure.
Can you bet both simultaneously?
Yes, nothing prevents betting pass line and don't pass at the same time, though as covered in craps strategy guide, this doesn't create a genuine hedge or advantage — it mostly cancels out variance while still paying the combined house edge on both bets (minus the specific barred-number scenario where pass line loses while don't pass pushes). It's not a mistake exactly, but it's not a value-creating strategy either.
Which bet suits which player
Pass line suits players who value the social, shared-excitement experience of live and physical table play, and who don't mind giving up a statistically negligible edge for that experience. Don't pass suits players who are indifferent to (or actively prefer) betting against the table's shared result, particularly in solitary RNG formats where the social consideration doesn't apply. Neither choice is wrong, and the difference in long-run cost between them is small enough that comfort and preference are legitimate deciding factors.
Frequently asked questions
Which has a better house edge, pass line or don't pass? Don't pass, very slightly — 1.36% versus pass line's 1.41%, a difference driven entirely by the barred-number rule on come-out rolls.
Why does don't pass push instead of win on a come-out 12? This is the barred-number rule, deliberately built in so the casino retains a structural edge even though don't pass otherwise mirrors pass line's opposite outcomes closely.
Is it ever considered rude to bet don't pass at a live table? Some players find it socially uncomfortable since you're betting against the table's shared excitement, though it's a completely legitimate, common bet with no actual rule against it.
Can I add odds to a don't pass bet the same way as pass line? Yes — don't pass odds work identically in structure (zero house edge) to pass line odds, just paying the inverse ratios since you're betting on the opposite outcome.
Does betting both pass line and don't pass at once create an advantage? No — it mostly cancels out variance while still paying the combined house edge on both bets, aside from the specific barred-number scenario.
Should beginners start with pass line or don't pass? Pass line is the more common starting point, mainly for its social simplicity and shared table experience — but don't pass is an equally legitimate, marginally better-edge alternative worth considering, especially for solitary RNG play.
